Hello @wilfredraeker,
Hello all of my syncs are failing for updating inventory from square to woo. It was working last week and now every sync is failing. I have Square as my sync setting. Let me know what other information you need me to provide and I will do so.
I understand products are failing to update/sync in WooCommerce with the data from Square.
Could you please share a copy of your site’s System Status? You can find it via WooCommerce > Status. Select “Get system report” and then “Copy for support”. Once you’ve done that, paste it here in your response.
Also, please enable the plugin logging from WooCommerce > Settings > Square.

Once you do, please attempt to manually sync products again. This time, if there are any issues with the synchronization process, some useful error logs should be thrown in WooCommerce > Status > Log(search of Square from drop-down menu).
You can copy&paste the theme directly here or in a text-sharing service like Gist.
Look forward to hearing back from you.
Hi,
We haven’t heard back from you in a while, so I’m going to mark this as resolved – we’ll be here if and/or when you are ready to continue.
Best.
